Don't buy anything in Whistler unless you must. There is a heavy glitz markup. I was up there a few years ago and I was interested in possibly demoing some Elans. I found a shop that carried them, but I ended up being more interested in a pair of Fischers that the guy in the shop was pushing. They were demos and it was April so he wanted to move them on. He was going to give me a super deal! Only $1088 with bindings! I passed on spending over a K on used skis and on the way home we dropped off some poles we rented, having broken one the day before we left. In the shop were an identical pair of skis to the ones I looked at in Whistler on sale, new, for $300. With bindings and tax I got out for less than $450.
Buy in the big city, it'll be a much better deal.
